Indian Journal of Experimental Biology. 2003 Feb; 41(2): 174-6http://imsear.searo.who.int/handle/123456789/59746Tomato pollen when treated with 24-epibrassinolide (EBR), it was observed that in vitro pollen germination was more tolerant to high temperature. A significantly higher in vitro pollen germination, enhanced tube growth and low pollen bursting were observed in presence of EBR at 35 degrees C. Since a preconditioning treatment of tomato plant was not required for these effects, it is concluded that EBR treatment increased basic thermotolerance of germinating pollen. This study provided the first evidence for EBR induced thermotolerance in germinating pollen.engAdaptation, Physiological --drug effectsCholestanols --pharmacologyGermination --drug effectsHot TemperatureLycopersicon esculentum --drug effectsPlant Growth Regulators --pharmacologyPollen --physiologySteroids, Heterocyclic --pharmacologyJournal Article
